Abstract:

An exhaust muffler for small marine craft that can be located in the rear portion of the bilge and straddle the drive shaft and the shaft log. The muffler has a shell formed from sides, ends, top and bottom walls. The bottom wall is provided with a concave depression to receive the shaft and shaft log. A preferred configuration of the depression is a semi-conical surface having a base proximate the inlet wall. Further, the top and bottom walls are configured to conform to the undersurface of the deck and the inside of the hull, respectively. An inlet pipe, or a multiple number of inlet pipes, receive exhaust gases and water from the exhaust manifold of the craft engine and direct this combination into the muffler above a water pool. Gases pass through the water pool and exit through an outlet pipe (or a plurality of outlet pipes). A downwardly extending conduit within the outlet pipe(s) provides a correct amount of lift such that an amount of water exits the muffler which is the same as the amount entering.
